Explore rewarding Engineer, Greece/Legacy Class Desk, Journeyman jobs, a specialized career path within defense systems engineering and sustainment. Professionals in this role are critical to the long-term operational readiness of complex military platforms, often focusing on legacy systems and international partnerships. These positions are ideal for engineers who excel at solving intricate technical challenges while navigating the unique protocols of defense acquisition and foreign military cooperation. Typically, individuals in these jobs serve as the central engineering authority or "Class Desk" support for specific aircraft or weapon system platforms. Their core mission is to ensure these vital assets remain mission-capable throughout their extended service life. A primary focus involves comprehensive sustainment engineering, which includes proactive troubleshooting, failure analysis, and the development of technical solutions to maintain system performance. A significant and constant responsibility is managing obsolescence—identifying components that are no longer manufactured and engineering suitable replacements or modifications to prevent fleet grounding. Day-to-day responsibilities are diverse and demanding. Engineers apply rigorous systems engineering principles to investigate issues, design modifications, and develop testing protocols. They prepare critical technical documentation such as engineering analyses, system evaluations, and change proposals. A key aspect of the role is technical leadership and coordination, requiring collaboration with various engineering divisions, supply chain management, and often with international stakeholders to align on sustainment strategies and modifications. This involves integrating efforts across multiple disciplines to implement solutions that address safety, performance, and regulatory requirements. To succeed in these journeyman-level jobs, candidates generally need a strong foundational background. A bachelor’s degree in an engineering or relevant technical field is standard, coupled with several years of hands-on experience in defense systems support. Highly valued skills include direct experience with sustainment activities and legacy system lifecycle management. Familiarity with Foreign Military Sales (FMS) processes and the ability to navigate associated compliance and coordination procedures is a common and critical requirement. Furthermore, due to the sensitive nature of the work, these positions typically mandate U.S. citizenship and the ability to obtain and maintain a government security clearance. For engineers passionate about extending the life of critical defense assets and working on complex, long-term engineering challenges, these jobs offer a impactful and stable career at the intersection of technology, logistics, and international defense cooperation.
